Over time, your browser accumulates temporary files—cached images, scripts, and site data—to speed up page loading. While helpful, outdated or bloated cache can slow performance, cause display errors, or interfere with website functionality. Many users hesitate to clear it, fearing they’ll lose saved passwords and login details. The good news: you don’t have to. With the right approach, you can purge unnecessary cache in seconds while preserving your credentials.
This guide walks through secure, efficient ways to clear browser cache on desktop and mobile devices—Windows, macOS, iOS, and Android—without sacrificing your stored logins. Whether you're troubleshooting a glitchy site or optimizing device performance, these methods ensure a clean slate without resetting your digital life.
Why Clearing Cache Matters (And Why Passwords Should Stay)
Browser cache stores copies of web resources like CSS files, JavaScript, and images. When you revisit a site, your browser retrieves these from local storage instead of downloading them again. This speeds things up but can lead to issues:
- Outdated versions of websites not reflecting recent updates
- Layout glitches due to stale stylesheets
- Failed logins or broken features after site changes
- Increased disk usage over time
However, clearing everything—including saved passwords—is inconvenient and risky. Re-entering credentials manually invites typos or phishing attempts. Worse, some users resort to writing passwords down, undermining security. The goal is targeted cleanup: remove only cached data while keeping passwords, autofill entries, and cookies tied to authentication intact.
“Clearing cache selectively is one of the most effective first-line fixes for web performance issues—and it should never require sacrificing user credentials.” — Dr. Lena Patel, Web Performance Analyst at NetSpeed Labs
Step-by-Step: How to Clear Cache Without Losing Passwords
The process varies slightly by browser and platform, but the principle remains consistent: disable password deletion during cache removal. Below are precise instructions for major browsers.
Google Chrome (Windows & macOS)
- Open Chrome and click the three-dot menu (top-right corner).
- Navigate to Settings > Privacy and Security > Clear browsing data.
- Select the time range (e.g., “Past hour,” “All time”). For thorough cleanup, choose “All time.”
- Check only the following boxes:
- Cached images and files
- Site data (optional, if tracking is a concern)
- Uncheck all other options, especially:
- Browsing history
- Cookies and other site data
- Saved passwords and payment methods
- Click Clear data. The process takes seconds.
Mozilla Firefox (Desktop)
- Click the hamburger menu (three horizontal lines) and go to Settings > Privacy & Security.
- Scroll down to Cookies and Site Data section.
- Click Clear Data… next to “Cookies and Site Data” and “Cached Web Content.”
- In the pop-up window, uncheck “Cookies and Site Data” and ensure only Cached Web Content is selected.
- Click Clear.
Firefox separates cache from login data more cleanly than most browsers, making this process straightforward and low-risk.
Safari (macOS)
- Open Safari and go to Safari > Settings > Privacy.
- Click Manage Website Data….
- Click Remove All—but wait! Before confirming, note that this removes cookies too.
- To preserve passwords, instead use an alternative method: enable Develop menu.
- Go to Safari > Settings > Advanced, then check Show Develop menu in menu bar.
- Now select Develop > Empty Caches.
- This clears only cached files—not cookies, passwords, or form data.
Microsoft Edge (Windows)
- Click the three-dot menu and go to Settings > Privacy, search, and services.
- Under “Clear browsing data,” click Choose what to clear.
- Select a time range (e.g., “All time”).
- Check only:
- Cached images and files
- Ensure the following remain unchecked:
- Browsing history
- Cookies and other site data
- Saved passwords
- Autofill form data
- Click Clear now.
Mobile Browsers (iOS & Android)
Clearing cache on phones requires extra caution, as some apps bundle data types tightly.
Chrome (Android)
- Open Chrome and tap the three-dot menu.
- Go to History > Clear browsing data.
- Select time range (choose “All time” for full cleanup).
- Enable only Cached images and files.
- Disable Browsing history, Cookies, and Saved passwords.
- Tap Clear data.
Safari (iPhone/iPad)
- Open Settings app (not Safari in-app).
- Scroll down and tap Safari.
- Tap Clear History and Website Data—but avoid this if you want to keep passwords.
- Instead, go back and tap Advanced > Website Data.
- Tap Remove All Website Data, then confirm.
- This clears cache and some cookies, but iCloud Keychain passwords remain safe.
“On mobile, always double-check which data categories are selected. A single wrong toggle can wipe months of saved logins.” — Marcus Tran, Mobile UX Consultant at AppFlow Design

Mini Case Study: Resolving Login Loops Without Resetting Credentials
A marketing manager, Sarah, reported being stuck in a login loop on her company’s internal CRM portal. After logging in, the system redirected her back to the login screen. She suspected a session conflict. Her IT team advised clearing cache—but she was reluctant, having recently updated several complex passwords stored in her browser.
Instead of wiping everything, she followed the selective method for Chrome: cleared only cached images and files, leaving cookies and passwords untouched. Within seconds, the site loaded correctly. The issue stemmed from a stale service worker script cached locally. By removing only the cache, she resolved the error without compromising her saved credentials or requiring a password reset.
This real-world example shows how precision matters. Full data wipes are rarely necessary; targeted cache removal often solves the problem faster and safer.

- ✅ Confirm and clear data
- ✅ Test affected websites immediately
Frequently Asked Questions
Will clearing cache log me out of websites?
Not necessarily. Logging out typically occurs when cookies are deleted. Since you’re only removing cached files (like images and scripts), your active sessions usually remain intact. However, some sites tie session data to cached components, so rare logouts may happen—but your saved passwords will still be available for quick re-login.
How often should I clear my browser cache?
Every 1–2 months for optimal performance. If you notice slow loading, distorted layouts, or outdated content, it’s a sign to clear the cache sooner. Power users or developers may do this weekly, especially when testing websites.
Is it safe to clear cache on shared devices?
Yes, as long as you avoid deleting passwords and cookies. On shared machines, consider using Guest mode or private browsing for sensitive tasks. Clearing only cache doesn’t expose personal data, but always verify what’s being deleted before confirming.
Final Tips for Long-Term Browser Health
Clearing cache is a reactive fix, but proactive habits prevent buildup and reduce the need for frequent intervention. Consider these ongoing strategies:
- Use Private Browsing for Sensitive Tasks: Incognito or Private windows don’t save cache or history, ideal for banking or shopping.
- Enable Automatic Cache Management: Some browsers (like Firefox) offer auto-purge settings based on disk usage.
- Monitor Storage Usage: In Chrome, go to Settings > Privacy > Site Settings > Storage to see which sites consume the most space.
- Bookmark Critical Logins: Even with saved passwords, keep a secure backup of essential URLs and credentials in a trusted password manager.
Conclusion: Maintain Speed Without Sacrificing Security
Clearing browser cache shouldn’t mean starting over with passwords. With careful selection in your browser’s privacy settings, you can eliminate cluttered, outdated files while protecting your login information. These methods work consistently across Windows, Mac, iOS, and Android, giving you control no matter the device.
Whether you're fixing a glitch, boosting performance, or preparing for a fresh browsing experience, knowing how to clear cache safely is a fundamental digital skill. Apply these steps today—quick, confident, and credential-safe.
